File extensions MCQ - Practice Questions with Answers

A PowerPoint 365 presentation is saved by default with the .pptx extension. This format is the modern Office Open XML presentation format and is meant for slide decks. The .xps format is used for fixed-layout documents, not editable presentations. The .xls extension belongs to older Excel workbooks, so it relates to spreadsheets. The .doc extension belongs to older Word documents, so it is used for text documents rather than PowerPoint presentations.

JPG, GIF and BMP are all common graphics or image file extensions, so that group fits the question exactly. CPX and GCM are not standard image extensions in ordinary computer-awareness usage, which weakens the group containing JPG, CPX and GCM. TCE is not a usual graphical file extension, although GIF and WMF relate to graphics. TCP is a network protocol abbreviation, not an image file format, even though JPG and BMP are graphical formats.

The extension .rar is used for compressed archive files, not for audio files. The extension .mid is associated with MIDI audio data, so it can represent audio-related content. The extension .wav is a standard waveform audio format used for sound files. The extension .mp3 is a widely used compressed audio format. Since the question asks for the extension that does not correspond to a valid audio file type, the archive extension .rar is the correct choice.
